"I barely manage," Damon told People. "I do have a little 'man area' that I can go to that is kind of mine that they don't know about."

However, he added that his secret room was not that high-tech, saying: "It's a couple of Sports Illustrateds and my iPhone, basically like a closet where I go and shut myself in if the oestrogen gets too crazy."

He continued: "The man cave is a work in progress, [but] that's my happy place."

Damon also said that his most cherished time is date nights with wife Barroso. He said: "[We] just literally go out to dinner and just sit and catch up and talk.

"We've got to be vigilant about it because if we don't make the time for it, it will never happen. We just make the time, basically."

Damon was speaking at this year's Environmental Media Awards, at which he was named 'Ongoing Commitment Honoree' for his work with Water.org, a charity he co-founded to bring clean water to people in developing countries.
